Crop pesticide residue removing agent

Abstract

The invention discloses a crop pesticide residue removing agent. The crop pesticide residue removing agent is prepared from the following raw materials in parts by weight: 20 to 30 parts of water, 8 to 10 parts of potassium hydrogen sulphate, 20 to 25 parts of solvent oil, 9 to 12 parts of titanium dioxide, 3 to 6 parts of zinc oxide, 4 to 6 parts of cadmium sulphide, 3 to 5 parts of tungsten oxide, 2 to 4 parts of tin dioxide, 1 to 3 parts of ferrous oxide, 4 to 6 parts of a pesticide emulsifier, 6 to 8 parts of potassium chromate and 7 to 9 parts of ferric hydroxide. According to the crop pesticide residue removing agent, the titanium dioxide is irradiated by utilizing the characteristics of high surface activity, strong ultraviolet light absorption capacity, excellent weather resistance, chemical corrosion resistance and the like of the titanium dioxide and matching the ultraviolet light in the sunlight; when the titanium dioxide is irradiated by the ultraviolet light, valence electrons jump to a conduction band so that photogenerated electron hole pairs are generated; the generated holes adsorb OH<-> on the surfaces of titanium dioxide particles and are oxidized with H2O to generate OH<-> free radicals, so that not the holes but the OH<-> free radicals directly participate in the photo-catalytic oxidation of organic substances in a pesticide; and therefore, the effect of degrading a pesticide is achieved.

Description

technical field [0001] The invention relates to the technical field of pesticide degradation, in particular to a crop drug residue remover. Background technique [0002] Refers to various plants cultivated in agriculture. A kind of organism, including food crops, oil crops, vegetable crops, flowers, grasses and trees. Edible crops are one of the sources of basic food for human beings. "Food is the most important thing for man", which expresses the relationship between people and food. A reasonable diet can bring health to human beings. Food self-sufficiency is the foundation of a country's sustainable development. The growth of crops is inseparable from scientific and technological production technology. With the development of science and technology, in order to prevent pests and pesticides from being used Developed and popularized, it is widely used in agricultural, forestry and animal husbandry production, environment and crop disease prevention. [0003] As people purs...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a pesticide residue remover for crops, which solves the problem that people pursue economic interests, and pesticides are widely used on crops, but pesticides tend to exist on the surface of crops and are difficult to remove, and then enter the human body Internally, the long-term accumulation of pesticide residues in the human body can easily cause poisoning, which seriously affects human health. With the use of pesticides, it will not only cause pollution and pesticide residues in vegetable fields in the suburbs of the city, but also destroy the biodiversity of the vegetable field system , enhance its resistance to pesticides, leading to the continuous increase in the amount and frequency of pesticide use, but the effect is getting worse and worse
